The Big Drencher uses our standard Easy Feeder calf feeding bottle with our new 'Big Drencher' probe. This probe is ideal for 'volume' drenching of mature cattle. The wide 70mm-dia neck makes for easy filling of drench products. The good hand-grip ensures the bottle is easy to handle in a drenching situation. For users who already own a Speedy Feeder or Easy Feeder (calf feeder bottle), the Big Drencher probe on its own will fit right on. Capacity 2.5 litres.
